Apparatus for generating system

An apparatus for generating steam, the apparatus comprising

• an evaporation element having an evaporation surface,
• a scale collection region,
• a heater disposed adjacent to the evaporation surface to heat the evaporation surface, wherein the heater is more proximate to the evaporation surface than to the scale collection region,
• a water inlet positioned relative to the evaporation surface so that water is fed onto the evaporation surface from the water inlet and forms a film on the evaporation surface such that said film is evaporated from said evaporation surface, and
• wherein the scale collection region positioned such that, during use of the apparatus, scale dislodged from the evaporation surface falls away from said evaporation surface into said scale collection region,
• wherein the apparatus is configured so that a flow of the water through the water inlet and onto the evaporation surface is controlled in dependence on a temperature of the evaporation surface so that substantially all the water fed onto the evaporation surface is evaporated from said evaporation surface without flowing from the evaporation surface into the scale collection region;
• further comprising a scale collection chamber and a channel disposed such that when the apparatus is rotated from an operational position, in which said water is provided to the evaporation surface, into a rest position, in which said water is not provided to the evaporation surface, scale dislodged from the evaporation surface will pass along said channel from said scale collection region and into said scale collection chamber which is configured to retain said scale.
